The waste generates from agro-waste fiber has huge quantity in Nigeria but the need for its full utilization is below average. The conversion of these wastes into polymer composite can lead to a new industrial revolution taking immerse advantages of these materials. This study investigated the influence of treated and untreated mango seed shell flour (MSSF) on the properties of polypropylene (PP) to manufacture mango seed shell flour-polypropylene composite (PP-MSSF). The MSSF was chemically modified with 5% wt NaOH solution at 4 h. The treated and untreated MSSF was injected in the PP at variant weight of 10, 20, 30, 40 and 50%, respectively. The compounding of MSSF and PP was done by the aid of injection molding machine. The manufactured PP-MSSF composite undergone mechanical test for the characterization of the composite. The variation of unmodified and chemically treated MSSF content was the main parameter in the properties of PP-MSSF composite. The results explained that the chemical modified MSSF displayed better properties than unmodified MSSF in the PP matrix by 26.28, 369.92, 58.97 and 465.71% for tensile strength, tensile modulus, flexural strength and flexural modulus, respectively. From the end result of this work, the produced PP-MSSF composite can be recommended in domestic application.
